Problems integrating new site

[Brewmeister]

I run a very large telecom network and have lurked in these forums for years. I have run into a problem that I simply cannot find info on so it was a good time to stop lurking and join the forum.

Our central switch is a 4 cabinet Avaya G3R11 that acts like a CO for the other switches. It has 3000 DIDs running into it that it routes to dozens of PBXs via T1's.

We had added a new switch a few years ago but never tried to integrate to the DCS network since it was using a stand alone vmail system. That vmail system is on its last legs so I decided that the time was right to bring it into the network.

I added trunk and signal groups, renumbered the stations to fit the dialplan, added them to the UDP tables, created route patterns for the calls and everything is working well. The names and station numbers come across just fine but I cannot for the life of me, figure out why I am unable to use Leave Word Calling to turn lights on and off at the remote site.

Users at the remote site can use the feature code to turn lights on and off just fine. I can use feature codes to turn lights on and off at any of the other sites. Trying to use LWC (which is what the vmail system uses) will not work from the central site to the remote site. It tries to access the correct trunk group but gets wave off/busy signal when dialing the access code.

The central switch is a Avaya Definity G3R11 using a TN 464 F at both ends. The far end switch is an Avaya G650/S8400 Ver 3.1. The Vmail system is a AVST CallXpress that has both standard and D82 Integration on 128 ports.

I have done the good old fashioned "Stare and Compare" with a working site that has the exact same config but so far, I have not a clue.

Thoughts anyone? Beuller?

Cheers,

Assuming that you are using DCS+ (ISDN based DCS), have you populated page 2 of the Signaling group form? On the Route Pattern screen do you heve the TSCs enabled? Within the Trunk Group, do you have a NCA-TSC Trunk Member: value entered?

I am indeed using DCS +.

Page 2 of the Sig Gp form is populated and enabled. Both entries (DCS and Audix) are Permanent and point to Mach ID 1 or 33, depending on which end.

Route Patterns on both sides were incorrect, I have changed them.

Trunks NCA-TSC are both set to member #1.

Still not working. Or, do I need to busy and release the board or trunk group to activate them?

You shouldn't have to do a busy/release. If you put a trace up on your station and try to do a LWC, does the trace indicate where it is failing?

Trace shows very little -

14:50:21 active station 7099 cid 0x5f1
14:50:23 dial *48969
14:50:23 term trunk-group 62 cid 0x5f1

When you dial *4 XXXX it gives a busy signal

Here is the Route Pattern -

Try doing 'test tsc x' where 'x' is the Signaling Group associated with the DCS trunks. If the TSCs don't pass, LWC won't work.

It looks like it is saying there is no D channel.

Huh?

The display in the phones is working perfectly, how can the D channel NOT be working?

I am, as they say, confused......

 

[Brewmeister]

Out of curiosity, I did the same test on several other PBX's in the network to see what I could see.

They ALL fail these same tests and all give the same error code.

All of the other systems work flawlessly so I suspect my issue lies elsewhere.
